Select empty on {html_select_date}

Hi,

   I'm trying to output a date dropdown with {html_select_date}, and
have the default selected fields blank.  My tag looks like this...

{ html_select_date prefix="start" month_format="%b" end_year="+5"
year_empty="" month_empty="" day_empty="" field_order="DMY" }

and it has an empty field for day, month and year at the top of the drop
down boxes, but by default it is selecting the current date.  How can I
(if I can) get it to have those empty values selected by default?  TIA
